Re: Y50 70 BIOS Can't Save Settings Or Exit

I've found an advice to remove cmos battery, main battery and memory and do several restarts combined with adding the cmos, memory etc. every few reboot sequentially.

It didn't work.

I'm still stucked with same configuration. Lenovo phone support said without Windows I/they cannot do nothing. Only sending the laptop for (after warranty) service. We will see, how much that will put me back...

It means the file grubx64.efi in antergos_grub directory will be loaded as first. Nothing else. And from no other drive but the 1st having the ID: f128f12b-fa3e-45b1-b5c9-f03c328498cb

So. Am I forever bound the Antergos? Well, no.

Long story short.

I've downloaded rEFInd package and REPLACED the antergos_grub directory with the content of rEFInd package, renaming the refind_x64.efi to grubx64.efiNow, after restart I've rEFInd boot menu (you can compare it to the BIOS boot menu) with the option for selecting boot source (including USB drives and optical drive (my case also via USB)).

This way I was able to install openSUSE and few other systems in between.

BUT!!!!

You must never erase the first partition with the rEFInd bootloader.

It will bind automatically systems installed on the next boot partition.

What if my hard drive got damaged or anything... Well, I thought of that too.

Using command:

sfdisk -d /dev/sda > HD_partitions.txt

you get a file named HD_partitions.txt containing IDs of all your partitions.
